Sorry about your onc’s personality or the lack thereof. Fortunately mine is personable and easy to talk to and the age of my grandchildren. I’m a young 74 year old because I claim it. Not everyday but 95 % of the time.
I’ve been in Ibrance, letrozole and exjavi for 19 months. It took 6 months to get the Ibrance regulated because of my white and red counts. I’m taking 75 mg 2 weeks on and 2 weeks off. My scans every 3 months show no progression as I had Mets on my spine, a double mastectomy with only 1 breast Her2 negative.
You are wise to gather information on what works for others. Sharing this with your onc as it is your body. I still have my hair a little thinner but happy to have it. Smile, take charge and live the life we have. Sending hugs and lifting you up.
